preparation example Construction

[0028] The preparation method for preparing the above-mentioned direct jet inkjet printing dispersion ink may further comprise the steps:

[0029] For the preparation of ultra-fine coated dye paste, firstly, the dye, polymerized monomer, co-emulsifier and initiator in the above ratio are stirred and mixed evenly to obtain the oil phase; then, the cationic surfactant in the above ratio is added to the deionized In the water, stir to make it completely dissolve to obtain the water phase; then, under the action of mechanical stirring, add the oil phase to the water phase dropwise, make it high-speed emulsified, and then place it in an ultrasonic cell pulverizer or a sand mill for fine emulsification for 10~120 minutes to make a fine emulsion; then, transfer the fine emulsion to a four-necked flask with a condensing reflux and stirring device, and after 5 to 30 minutes of nitrogen gas, at a stirring speed of 250-600 rpm, the temperature is raised to 60 React at ~90°C for 1-24 hour...

Embodiment 1

[0033] Disperse Red 4, 10g of C.I. Disperse Red 4, 12g of styrene, 0.54g of hexadecane and 0.4g of azobisisobutyrocyanide were stirred and mixed uniformly as the oil phase; 2g of cetyltrimethylammonium bromide was dissolved The water phase was prepared in 50 g of deionized water; the above oil phase was added dropwise to the water phase under mechanical stirring, emulsified at high speed and placed in an ultrasonic cell pulverizer for 10 minutes to obtain a fine emulsion. Transfer the miniemulsion to a four-neck flask with condensing reflux and stirring device, pass nitrogen gas for 30 minutes, then raise the temperature to 60°C at a stirring speed of 600 rpm, react for 24 hours, and filter with a 500nm filter membrane. You can get ultra-fine coated dye paste.

[0034] Weigh 50g of ultra-fine coated dye paste, then add 10g of ethanol, 10g of ethylene glycol, 5g of sodium lauryl sulfate, 0.1g of AFE-7510, 0.1g of phthaloaniline and 23.8g of water and mix evenly. Stir with a st...

[0036] Mix 20g of C.I. Disperse Red 152, 6g of butyl acrylate, 0.39g of cetyl alcohol and 0.25g of ammonium persulfate evenly as the oil phase; dissolve 1.2g of cetyltrimethylammonium bromide in 50g of deionized water was used to prepare the water phase; the above oil phase was added dropwise to the water phase under the action of mechanical stirring, and after high-speed emulsification, it was placed in an ultrasonic cell pulverizer for 10 minutes to obtain a fine emulsion. Transfer the miniemulsion to a four-neck flask equipped with condensing reflux and stirring devices. After passing nitrogen for 30 minutes, at a stirring speed of 600 rpm, raise the temperature to 90°C, react for 12 hours, and filter with a 500nm filter membrane. You can get ultra-fine coated dye paste.

Abstract

The invention discloses a direct injection ink-jet printing dispersion ink. The direct injection ink-jet printing dispersion ink is characterized by comprising 100 g of the following materials: 20 g to 50 g of superfine coated dye paste, 10 g to 50 g of water-soluble cosolvent, 0.1 g to 5 g of surfactant, 0.1 g to 2 g of defoamer, 0.1 go to 0.5 g of bactericide, 0.1 g to 1 g of pH adjuster and the balance of water. The superfine coated dye paste is formed in the way that oil phase and liquid phase are emulsified and then nitrogen is fed, wherein the oil phase is formed by mixing and stirring 10 g of 50 g of dye, 3.3 g to 60 g of polymerized monomer, 0.33 g to 3 g of co-emulsifier, 0.1 g to 5 g of initiator, and the liquid phase is formed by stirring and dissolving 0.1 g to 20 g of cationic surfactant and 50 g of deionized water. Superfine coated dispersed dye is prepared through a miniemulsion polymerization method, so that the dispersion stability and the fluency of the direct injection ink-jet printing dispersion ink are improved, the probability nozzle blockage is reduced, and the printing time is prolonged.

Description

technical field [0001] The invention relates to a direct-injection inkjet printing disperse ink and a preparation method thereof, in particular to a method for improving the dispersion stability and fluency of the direct-injection disperse ink and improving the grafting rate and color fastness of fabric inkjet printing Dispersed ink for direct jet inkjet printing and a preparation method thereof. Background technique [0002] Inkjet printing technology is a new, low-energy, green and environmentally friendly printing method. This technology uses a computer-controlled jet printing system to print the designed pattern directly onto the fabric. Compared with the traditional inkjet printing, it abandons the complex link of plate making in traditional printing, greatly improves the printing accuracy, realizes small batch, multi-variety, multi-color and personalized printing, and has broad development prospects. Ink is an important consumable in digital printing production, and ...
